Strange Question......I guess hotter magma rises to the surface of the mantle while colder magma sinks closer to the center....Sort of like a lava lamp!
When you plug in a lava lamp, it heats up at the bottom, just like the earth's magma. It's hot at the bottom and it cools at the top.

JudyThe Earth's mantle is a solid layer of rock beneath the Earth's crust, whereas a lava lamp contains liquid wax that constantly moves around due to heat from a light bulb underneath. The mantle is a natural geological feature of the Earth, while a lava lamp is a decorative household item.
Lava Lamp:
- requires an external electrical heat source
- man-made
- constructed of glass and metal
- paraffin inside moves quickly relative to magma in mantle
- can be purchased
- is transportable
- comes in a variety of colors
- easily observable
- required temperature of operation less than 200o F
Earth's mantle:
- occurs naturally
- powered by Earth's internal heat
- consists largely of ultra-mafic rock
- temperatures can reach 4000o F
- cannot be purchased, observed directly, or transported
- is rather large compared to lava lamp, comprising 83% of Earth's total volume
- movement of rock is extremely slow compared to movement of paraffin in lava lamp

What kind of landforms are made by volcanoes?
It when plates colliding and making the volcanos also when the earths crust is open and the mantle or lava comes out,
What is earths mantle heated by?
Earth's mantle is mainly heated by the decay of radioactive isotopes and residual heat from the formation of the planet. This heat causes convection currents in the mantle which drive plate tectonics and other geological processes.
How hot does the lamp at the bottom of a lava lamp get?
The lamp at the bottom of a lava lamp typically heats up to around 150-200 degrees Fahrenheit (65-93 degrees Celsius). This temperature is necessary to melt the wax and create the mesmerizing lava lamp effect.
What does the heat source of the lava lamp represent in the Earth?
The heat source of the lava lamp represents the Earth's core, which is made up of a solid inner core and a liquid outer core composed of hot, molten metal. Just as the heat source in the lava lamp causes the wax to rise and fall in a continuous motion, the heat from Earth's core generates movement in the mantle, leading to processes like plate tectonics and volcanic activity.
Why does lave in a lava lamp move slower then the water around it?
The lava in a lava lamp moves slower because it is denser than the surrounding water. Due to differences in temperature and density, the heated wax (lava) rises to the top of the lamp, cools down, and then sinks back to the bottom. This creates the slow, mesmerizing movement you see in a lava lamp.
